| RedHawk Linux Release 5.1 Now Available Concurrent has released a new version of its RedHawk Linux real-time operating system, RedHawk Linux 5.1. RedHawk Linux is widely used in time-critical applications in simulation and training, data acquisition, imaging, financial services and process control. RedHawk guarantees that a user-level application can respond to an external event in less than 30 microseconds. New features in RedHawk Linux 5.1 include: - Non-uniform memory architecture (NUMA) performance optimization; - 2.6.23 Linux Kernel; - Full compatibility with Red Hat Enterprise 5.1; - Support for the latest Intel and AMD quad-core processors and chipsets; - User-level (UIO) device driver support; - The latest NVIDA graphics drivers optimized for real-time performance; - New lockless kernel trace feature for enhanced real-time debugging and performance analysis. RedHawk Linux 5.1 improves the determinism of real-time processes in non-uniform memory architecture Opteron -based systems. RedHawk ensures that all pages of a real-time process are local to a given node and that no other process' pages are using that same node. RedHawk can automatically duplicate libraries and other modules as needed and maintain them simultaneously in multiple nodes to maximize performance. Support for the latest Intel and AMD quad-core processors and chipsets provides for more computing power in smaller, more cost effective, energy efficient packages than previously possible. RedHawk 5.1 supports user-level (UIO) device drivers which allow developers to implement a user-space, non-kernel driver for almost any type of hardware. RedHawk also includes the latest available NVIDIA graphics driver specially optimized for real-time performance by Concurrent. The enhanced driver allows applications to achieve maximum determinism during image rendering. The performance of Concurrent's NightStar tools, an integrated package for developing time-critical Linux applications, has been further enhanced by the introduction of RedHawk 5.1. NightStar tools run with minimal intrusion, thus preserving application execution behavior and determinism. Users can quickly and easily debug, monitor, schedule, analyze and tune applications in real-time. RedHawk 5.1's new lockless kernel trace feature eliminates any contention when multiple CPUs attempt to log trace points simultaneously. This feature is important as users scale up to systems with up to 32 cores. RedHawk Linux is included with all Concurrent iHawk real-time multiprocessors, ImaGen visual servers, MediaHawk Content Delivery Systems and is also available as a software-only product. Concurrent real-time platforms can be configured with up to 32 CPU cores in one system chassis running a single copy of RedHawk Linux. write your comments about the article :: © 2008 Networking News :: home page |
